I have 3 different DB-s, I am working with. I have no problem linking the data in. The user is in DB-a. My problem is I need the little bit of tricky code to check my DB-A's plainid the DB the user is in. To check the DB-A's planid against DB-B' plainid then use the data to fill a sub-form. If there is not a match go to DB-C and use that data to fill in a sub-form. The sub-form data is for display only, not to update.
